The Shelter IMMEX Program & Other Types of IMMEX in Mexico

Blog updated May 2026

Introduction to Shelter Services in Mexico

The shelter IMMEX program has become one of the most efficient ways for foreign manufacturers to operate in Mexico. They combine shelter services with the country's IMMEX (Industria Manufacturera, Maquiladora y de Servicios de Exportación) framework into a single operating model.

Benefits of the Shelter IMMEX Program

Shelters are typically owned and operated by Mexican companies that provide a comprehensive range of services to foreign companies, including:

• Manufacturing facilities: Shelters offer state-of-the-art manufacturing facilities equipped with the necessary machinery and equipment to support various industries.
• Infrastructure: They provide essential infrastructure, such as utilities, transportation, and logistics services.
• Human resources: Shelters assist with recruitment, training, and management of the workforce.
• Customs and regulatory compliance: They ensure compliance with Mexican customs and regulatory requirements.
• Administrative services: Shelters handle administrative tasks, such as accounting, payroll, and legal matters.

The shelter IMMEX program provides a favorable legal and tax framework for foreign manufacturers operating in Mexico. By combining shelter services with IMMEX certification, companies access the country's strategic location and competitive advantages without setting up their own Mexican legal entity.  

Introduction to the IMMEX Program

Navigating the world of international manufacturing can be complex, especially when entering new markets. For global manufacturers, establishing operations in Mexico offers a range of benefits, particularly through the IMMEX program. The IMMEX  program allows foreign manufacturers to temporarily import goods and materials into Mexico without paying VAT (with VAT Certification) and may reduce import duties and have virtual transactions of goods, provided these materials are used in the production of goods for export. Additional programs may be required.

IMMEX companies typically operate as a cost center in Mexico. They do not maintain a profit locally. So instead of paying an income tax in Mexico, the Safe Harbor ruling applies. Read more about finance and tax in Mexico.

Understanding the different types of IMMEX is crucial for manufacturers aiming to maximize efficiency and compliance. This guide will explain the different IMMEX types and help you choose the right one for your business.

Key Types of IMMEX

1. Industrial IMMEX (“IMMEX Industrial”)

Definition: The Industrial IMMEX is the most common type, allowing companies to import raw materials and components for manufacturing, transforming them, and then exporting the finished products.

Key Characteristics:

• Ideal for Manufacturing Activities: This type is perfect for companies engaged in manufacturing and assembly operations.

• Work Breakdown Structure (WBS): Companies must provide a detailed WBS outlining production processes.

• Duty Deferral: Imported materials used in the manufacturing process are exempt from value-added tax until they are exported as finished goods.

2. IMMEX Holding Company (“IMMEX Holding”)

Definition: The IMMEX Holding program is designed for organizations managing multiple manufacturing companies under a single IMMEX registration.

Key Characteristics:

• Streamlined Administration: Facilitates the management of several manufacturing subsidiaries, simplifying compliance and administrative tasks.

• Shared Privileges: All subsidiaries under the IMMEX Holding benefit from the same import and export privileges as the Industrial IMMEX.

3. IMMEX Services (“IMMEX de Servicios”)

Definition: This type of IMMEX caters to companies that provide services supporting the production of export goods.

Key Characteristics:

• Support Services: Ideal for logistics, maintenance, quality control, and other support services.

• Temporary Import: Allows the temporary import of equipment and materials necessary for service provision, enhancing operational flexibility.

4. IMMEX Shelter (“Empresa de Servicios Especializados de Ensamble – Maquiladora”)

Definition: The IMMEX Shelter program enables foreign companies to establish operations quickly by partnering with an existing Mexican company that acts as a shelter.

Key Characteristics:

• Faster Entry Point: Leverages the shelter company's existing infrastructure, permits, and experience for a faster market entry.

• Administrative Support: The shelter company handles administrative tasks, compliance, and IMMEX management, allowing foreign companies to focus on core operations.

5. Third-Party IMMEX ("IMMEX Terciarización")

Definition: A certified, third-party IMMEX company in Mexico provides manufacturing operations services to another certified IMMEX company that does not have installations in Mexico. This could allow non-manufacturing IMMEX companies an ability to conduct productive processes in Mexico.

Key Characteristics:

• No Factory Required: Utilizes a third-party, existing structure in Mexico, so the start up time could be decreased.
• Flexibility: Works similar to a contract manufacturer, with added benefits of foreign-based service transactions, free of Mexican VAT.
  
  

Choosing the Right IMMEX Type

Selecting the appropriate IMMEX type is vital for aligning the program's benefits with your business needs. Consider the following factors:

• Nature of Business Operations: Determine whether your primary activities involve manufacturing, support services, or other functions.

• Company Structure: Evaluate if your organization consists of a single entity or multiple subsidiaries.

• Control and Administrative Burden: Decide the level of control you want over operations and the amount of administrative tasks your company can handle.
